LuLuLun Hydra EX Mask Exosome and Key Ingredients

The exosome in LuLuLun Hydra EX Mask is listed as human adipose-derived mesenchymal cell exosome (ヒト脂肪由来間葉系細胞エクソソーム), a skin-conditioning ingredient whose name shows it comes from mesenchymal cells of human fat tissue. LuLuLun states that it contains no stem cells. Around it, LuLuLun adds what it calls a translucency formula of glutathione, arbutin and a vitamin C derivative, and four supporting ingredients that it says tend to decline with age: EGF, human-type ceramides, hyaluronic acid and collagen.

The box sums this up as an “ageing care mask with 2 kinds of lipocapsules and 4 kinds of useful ingredients for everyday”. The sheet is LuLuLun’s newly developed Melty feel sheet, which LuLuLun says wraps the skin softly, as if between layers of water.

LuLuLun Hydra EX Mask lists 35 ingredients, including the exosome, glutathione, arbutin, vitamin C derivative, EGF, two ceramides, hyaluronic acid and atelocollagen highlighted below. The preservatives are phenoxyethanol and methylparaben.

How to Use LuLuLun Hydra EX Mask

Use LuLuLun Hydra EX Mask every morning and night after washing your face, in place of toner, and leave it on for about 5 to 10 minutes, as LuLuLun’s FAQ recommends for its lotion-type masks. Then seal in the moisture with a milk or cream.

1. Unfold the sheet and fit the eye and mouth holes to your face.
2. Hold the inner corners of your eyes and press the sheet to push out any air.
3. Pull the slits below the cheeks up along your jawline, on each side.
4. Smooth the whole sheet with your palms and leave it on for about 5 to 10 minutes.
5. Take it off, fold it and wipe your face with it, then pat in the essence.
6. Finish with a milk or cream.

LuLuLun Hydra EX vs Hydra PD and Other Hydra Masks

Choose Hydra EX for bounce and a translucent look with exosome and glutathione, or Hydra PD for firmness and gloss with two PDRNs; both cost the same. On LuLuLun’s Hydra chart, EX sits on the moist side, just before PD and 5ALA, the most moisturising masks in the series.
